How does this skill improve error handling?

It implements a custom error class hierarchy and uses Result types to ensure that error states are explicitly handled, making your application logic more predictable and type-safe.

Can this skill help with runtime data validation?

Yes, it provides patterns for Type Guards and Assertion functions that safely narrow 'unknown' or 'any' types into validated, typed objects during execution.

What are branded types in this TypeScript skill?

Branded types are a pattern used to differentiate between primitive types, such as preventing a UserId string from being accidentally used as an OrderId string, ensuring domain safety at the compiler level.

Is this suitable for existing TypeScript projects?

Absolutely. It is designed to help refactor existing codebases toward 'strict: true' standards and implement more maintainable module organization like barrel exports and dependency injection.

What architectural patterns does it include?

The skill includes implementations for the Repository pattern for data access and the Builder pattern for complex object or query construction, all with full TypeScript generic support.

API開発

Implements advanced TypeScript patterns and strict typing strategies to ensure type safety and code maintainability.

概要

This skill equips Claude with specialized knowledge of advanced TypeScript implementation patterns, moving beyond basic types to enterprise-grade architectures. It provides structured guidance on creating branded types for domain safety, utilizing discriminated unions for state management, and implementing robust error hierarchies. Ideal for developers aiming to leverage TypeScript's full power for mission-critical applications, it ensures that every line of code adheres to strict typing best practices, improves developer experience, and minimizes runtime errors through sophisticated compile-time checks.
